Do you think it could be possible? Guess what?
Apparently it's already happened! And NASA videotaped the whole thing!
If Kohler is to be believed, then astronauts have been sexing it up in space for some time now and have been taping it for research purposes. And, given the tight confines of spacecraft and the need for at least one other person to be present to tape the encounter, it seems that any such mission would turn out to be nothing more than a porno movie shoot under very difficult circumstances.
"The issue of sex in space is a serious one," [French writer Pierre Kohler] says. "The experiments carried out so far relate to missions planned for married couples on the future International Space Station, the successor to Mir. Scientists need to know how far sexual relations are possible without gravity."
He cites a confidential Nasa report on a space shuttle mission in 1996. A project codenamed STS-XX was to explore sexual positions possible in a weightless atmosphere.
Twenty positions were tested by computer simulation to obtain the best 10, he says. "Two guinea pigs then tested them in real zero-gravity conditions. The results were videotaped but are considered so sensitive that even Nasa was only given a censored version."
I just hope they picked the lead actors very well.
